The construction and operation are as follows:

1 represents the bed ofthe machine.

2, 2, and 3 are brackets at the rear of the bed to'support thedriving-shaft4 and the cam-shaft 5. The said shafts project beyond thebracket 3 and are shown as broken at Fig. 1. On these projecting ends,but not shown, are gears which transmit motion from the driving-shaft 4to the cam-shaft 5, and on the outside of the gear on the saiddriving-shaft is also the driving-pulley. (Not shown.) f

6 is a bevel-gear on the end of the camshaft which registers with thebevel-gear 7 of the short shaft 8, mounted in the standard 9 at theeXtreme left of the bed. The shaft 8 carries the cam-plate 10.

11 is a lever pivotally mounted in the standard 12, which lever carrieson one end the roll 13 to engage with a cam-groove in the saidcam-plate, while the other end is provided with the segment-gear 14,adapted to register with the pinion 15, mounted on the short shaft 16,journaled in the standards 17.

`18 is a gear mounted on the opposite end of shaft 16, which gearregisters with the pinion 19, mounted loosely on the lower feedrollshaft 20. This shaft, together with the upper feed-roll shaft 2l, ismounted in the standards 22 and 23.

24 and 25 are the wire-feed rolls. (See Figs. 2 and 4.) The two-feedroll shafts are connected together by means of the gears 26 and 27. Onthe outer projecting end of thelower feed-roll shaft 2O is theratchet-feed, consisting (see also Fig. 41) of the ratchet-gear 28,rigidly attached to the shaft .20. 29 is a plate loosely mounted on saidshaft `and rigidly connected or integral with the pinion 19, and

'it carries the pawls 30 and 31, adapted to engage with the saidratchet-wheel, and the same are held in engagement by their springs 32and 33. When, therefore, the cam-shaft 5, Fig. 1, is running to operatethe rnechan- I ism necessary to make the heddle, it will alsocommunicate a continuous motion to the short shaft 8 through themediumof the bevel-gears 6 and 7, before mentioned. The cam-groove (notshown) in the face of the cam-plate 10 will give an intermittent motionto the wirefeed rolls through the medium of the vibratory movement ofthe segment-lever 1 1. One stroke of this lever in the direction ofarrow w, Fig. 2, will through the medium of the gears cause thefeed-rolls 24 and 25 to rotate sufliciently'to feed forward an amount ofwire to make one complete heddle. The return movement of thesegment-lever 11 to its normal position (shown at Fig. 2) will cause thepawls and y31 to slip over the teeth of the ratchet-wheel 28 and bein'readiness to rengage therewith on the next forward stroke.

34, Figs. 1 and 4, is a lever pivotally supported in the standard 35 onthe upper surface of the raised portion 1fL of the bed. The rear end ofsaid leverv carries the roll v36, adapted to engage the cam 37 on theshaft 5. The opposite end of this lever carries the adjusting-screw 38.(See also Figs. 2 and 12.) 39 is a wire-clamp pivotally supported on thepin 40 of the standard 4l, against which clamp the said screw 38 isadapted to engage at the proper time to grip the wires and prevent theirbeing withdrawn on return of the yfeeding mechanism.

42, Figs. 1 and 5, is a lever pivotally sup-` ported on the standard 43and carries a roll at its rear adapted to operate in the grooved cam 44.The forward end of said lever is pivotally supported to the slide 45, asshown. (See also Figs. 2, 12, and 13.) This slide carries the folder 46,(seen also at Figs. 17, 21, 22, 23, and 27,) adapted to bend the end ofthe wire around the former, presently to be more fully described. Thisfolder is attached tothe uprights 45n of the said slide at IOC IIO

IZO

the sides, while its central portion p, Fig. 27, is made quite thin, inconjunction with the slot 45" of said slide, to permit said folderpassing over the wire-guide 47, presently to be more fully described.The folder is provided with the spring-jaws 46a, whose inner faces havethe grooves 4S to receive the wire.

49, Figs. 12 and 13, is the lower slide, in which the slide 45 operates,while the slide 49 operatesin the support 50, projecting from the raisedportion of the bed. The wire-guide 47 projects from this first orlowerslide and is provided with the hole 47 therethrough, Fig. 6, toadmit the wire. The caps 50 hold the slide 49 in place, while the caps45c hold the slide 45 in working engagement with the slide 49. c

51, Figs. l and t, is the cutter-bar, operatively mounted in-thestandards The rear end of this bar is provided with the roll 515', whichengages with the cam 54. 55 is the cutter in the end of said bar and isadapted to operate against the inner face of the beforeunentionedwire-guide 47 to sever the wire.

56, Figs. 1 and 7, is one of the bending-bars operating in the standards57 and is controlled and governed in its reciprocating movements by thecam-groove 5S of the cam 5S. and is adapted to engage the end of thewire and bend the same over the former G4, presently to be described.

56a, Fig. 1', isa similar bending-bar to the one just described, beingmounted in the standards 57 and is adapted to engage in the same mannerwith the cam 58h.

59, Figs. 1 and 7, is one of the levers that control the movements ofthe vertically-operating trod-eye formers, presently to be described. GOis astandard in which said lever is pivotally supported. Said leverextends below the bed and carries the roll 61 to engage with the caniportion G2 of the cam 58a. The forward end of this lever is connected tothe pin 99 (see also Figs. 2, 12, 13, and 16) of the forked end of theformer 64. The lower end G4" of the former is diamond shape, as shownat` Figs. 7 and 1G, so as to give an equivalent form to the rod-eye inthe fnd of the heddle. 65 is a bracket attached to the slide 49, inwhich bracket such former is adapted to have a vertical movement. Thewires (5G, of which the heddle is made, are of double strands and aresoldered together, so as to make practically a single wire.v These wiresbeing fed through the axis of the machine, of which the center of thesaid former is in a direct line, necessitates the beveling of the lowerend of this former at y, so that when said former descends to its lowestvertical position, as shown at Fig. 1G, this beveled end will force saidwires to one side of said former, as shown, in readiness to be foldedthereabout.

The mechanism on the opposite end of the machine necessary to form theother rod-eye The end of this bar (see also Figs. 21'

is precisely similar to that j ust described, except that thecutting-off tool and its appurtenances are omitted. A brief description,therefore, of these simi-lar parts will suffice.

42, Figs. 1 and 3, is the lever, mounted on the standard 43, and it isoperated by the cam' 44, that operates the slide 45d, which slidecarries the other folder 4Gb, mounted upon the supports 450. 49 is thelower slide, and 45f and 50h are the caps for holding them in place, allmounted on the support 50C. The lower end of the former (541 is alsodiamond shape, as shown at Figs. 21, 22, and 23. The forked end of thisformer also carries the pin (33, to which pin is connected theoperatinglever 59, mounted upon its standard (i0fL and engaging the cam58h of shaft 5.

(37 and 67, Figs. 1 and 3, are the twister or winding shafts, journaledin the standards GS, Gf), 70, and 71. On the outer end of these shaftsare rigidly mounted the wireholding chucks 72, 73, 74, and 75, whosejaws 76, 77, 7S, and 79 (see also Figs. 21 and 23) are controlled by theforked levers S0, S1, 82, and 83, mounted on their standards 81, 82, and83, and said levers are operated by their respective cams 80", Sib, 82",and 83h, mounted upon the cam-shaft 5. S4 and 84 (see also Fig. 11) arepinions integral with the said winding-shafts and are thus made integralby reason of the fact that the shafts, as well as the chucks, areprovided with the slots S5 85, which slots extend just beyond the centerof said shafts for the reception, as well as the delivery, of theheddle-wires, presently to be more fully described. These pinions areengaged by the gears S6 and mounted on the shaft-s S6b and 8Cc of thestandards 86d and S69. On these shafts are also mounted the pinions Sfand 86g, adapted to be engaged by the segment-levers 87 and 87, whichlevers in turn are pivotally supported in the standards S71 and 87 andare operated by the cams S7d and S7e on the cam-shaft 5. These leverswill impart a reciprocating motion to the winding-shafts just described.

The mechanism necessary to form the warpeye ofthe heddle is shown atFigs. 1, 9, and 10. SS is a bar operating in the standard 89. One end ofthis bar carries the roll 88a to engage a groove in the vertical face ofthe cam 82". Sub is the eye-forming tool, projecting from the inner endof said bar. SS is an arm adjustably secured to said bar. To the upperend of this arm is attached the rod SS, having a reduced portion 88Cadapted to operate in a hole provided 'in the end ofthe rod SSf. 88g isa lever pivoted to the standard 89 and to the said rod SSf, while thelower end of said lever is pivoted to the sliding block S9, adapted tooperate in the opening 89b of said standard. S9c is a tongue projectingfrom said sliding block, which tongue supports the upper and loweranvil-jaws S9d and S90. These jaws are operatively secured to saidtongue by 'means of the vertical rods S92 extending loosely through saidjaws and IOC) IIO

tongue. These rods (see particularly Figs. 9 and 10) are surmounted bythe .adjustingnuts 89g, while the springs 89h areplaced on said rodsbetween said nuts and jaws, so that said jaws will be forced openagainst the closing tension of said springs.

. On each side of the bar 88, Figs. 9, 21, and 23, are the twosheet-steel wire-centering devices 90, having the forked opening 90a intheir forward ends. These centering devices are secured to the verticalprojection 90b of the slidingbar 90. This bar is guided in the standard89 and carries the roll 90d to engage with the cam-swell 82c of the cam82", whereby a transverse motion is imparted to said bar for thepurpose. presently to be more fully described.

90e is a retractile spring secured to the upright portion of the slidingbar 90c and the standard 89 to keep the roll of said bar en? gaged withthe periphery of the cam 82".

The object of the centering device just described is to bring the twotwin wires 66 on each side of the axis of the winding-shafts and on aline with such axis, so that when the eye-forming tool 88b is broughtforward the meeting faces of said wires will be in exact line with thepoint of said eye-forming tool. The centering device 90 will thereforemove forward'first and locate the wires, as before mentioned, then thebar 88 will be carried forward, and when the shoulder 88h of the rod 88dstrikes against the end of the rod 88f 'the sliding block 89a. will bemoved forward l i Y.4.0

toward the Wires and the jaws 89d 89e will reach such forward positionjust before the eye-forming tool engages to separate said wires, so thatsaid jaws will form an anvil to support the wires during the Asplittingor separating operation, as shown at Fig. 10. On the reverse motion tobring the eye-forming tool and the anvil-jaws' back to their normalposition, as shown at Fig. 9, the pin 88i is secured to the reducedportion 88e within the rod 88f and such pin projects through anelongated slot (not shown) in the upper surface of such rod, so thatwhen the bar 88 moves back said pin will engage that end ofsaid slotfarthest from the said anvil-jaws and cause said jaws to be carriedback. 91 is an adjustingscrew in the standard 89 to limit such backwardmovement of the sliding block, and 91a is another adj usting-serew toengage with the upper part of the lever 89lg toglimit the forwardmovement'of said block.

Devices for guiding or centering the wires between the jaws of the endchucks 72 and 75 are shown at Figs. 18, 19, and 20, and asl thesecentering devices are precisely alike both as regards their constructionand operation a brief description of the Aone shown at Figs. 18, 19, and20 will suffice. 92 is a bar resting on the upper face of themachine-bed and kept in place by the housings 92a. 92b is a roll bearingagainst the face of theI cam b and is held thereagainst by theretractile .spring 92C. 92d is a cam projection on the i v ,Y l L626,521

periphery of the cam 8Ob to engage with said roll and actuate said bar.92e is a T-shaped head on the inner end of the sliding bar 92,

'adaptedto support the adjustable standard 93. To the upper end of thisstandard is attached the rod 93a, whose reduced portion 93hA telescopesintothe rod 93. 93d is an elongated slot in the face of this rod 93C, inwhich the pin 93e of said reduced portion operates to effect the returnof those parts connected with rod 93c to their normal position and insubstantially the same manner as previously described with respect tothe centeringA device connected with the warp-eye-forming device. 93f isa lever pivotally secured to the standard 94, sliding block 95, and therod 93C. 94a is an arm projecting 'from this sliding block, and it hasthe V-shaped opening 94th at its free end. 94C is a similar armprojecting from the standard 93, and it is also provided with theV-shaped opening or notch 94d on its free end. These wire-centerin garms are adapted to bring the four strands of wire central with the jawsof their respective chucks. In other words, when the ends of the twinWires are bent around their respective formers 64a and 64d it will beobserved, Fig. 23, that there will be four strands parallel with eachother due to the folding of the ends of the wires against the -body ofthe heddle. Therefore it is absolutely necessary that the jaws of thechucks should engage all of these wires, and for that purpose thecentering devices just described areprovide'd. It will be observed thatthe said wire-centering arms 94:1 and 94 pass by each other, as shown atFig. 20, and are so nicely adjusted with respect to their centralposition that the wires are brought within the embrace of the jaws ofthe chucks. 93g is an adjusting-screw to limit the throw of lever 93",while screw 93h limits the travel of the block 95, as shown at Fig. 18.

The wire-centering device just described and operating close to the jaws76 of the chuck 72 is duplicated by a similar device located close tothe jaws 79 of the chuck 75; but owing to the confusion that would ariseby placing them in the complicated and reduced* drawing shown at Fig. 1they are therefore omitted from such view. All therefore that is seen insaid view are the actuating mechanisms, one of which has already .bee-ndescribed. The other consists of the bar 95, which carries the roll 95ato engagewith the projection 95, situated on the periphery of the cam83h. said bar, and 96 are the housings therefor.

The chucks mounted on the winding-shafts are constructed as follows: Theshell 75, Fig. 14, is constructed with a groove in its periphery toreceive the rolls of its forked lever after the manner of all suchdevices and by IOO lOS

TIO

c is the T-shaped end of means of which such shell is given a lateral ofthe chuck and the jaws. The said jaws, Fig. 15, are provided with thegroove 79a, which extends along the level portion 7 9b .and the beveledportion 7 9C. In this groove is placed the ball 75, Fig. 14, backed upby the spiral spring 75C, placed in a hole drilled through the outershell of the chuck, and 75d isashortscrew that holds said springinplace. The other jaw is likewise provided with ball 75e, spring 75f, andscrew 75g. This feature of the ball-bearing will enable the jaws to beopened or closed without that friction which is otherwise unavoidablewhere two taper-surfaces are brought in Contact with each other. Inclosing the jaws Y the balls will roll up the inclined surfaces thereof,and when they reach the straight portion said jaws will be closed, sothat it will require but the slightest pressure of the clutch-lever todislodge them. 97, Fig. 8, is a spring adapted to throw the jaws open.

The operation of the machine just described is as follows: All partsbeing in their normal position, as shown at Fig. 1, the double strand ofwire is brought from a reel (not shown) through the feeding-rolls, andthese rolls are so geared, as previously described, that a downwardmovement of the lever 1l will feed forward sufficient wire to form acomplete heddle. The wire passes beneath the clamp 39, Fig. 12, throughthe guide 47 and into the grooves or slots of the chucks andwindingshafts until the end (see Fig. 21) has projected beyond theformer 64far enough to make the rod-eye. The centering devices 90 arethen brought forward, the jaws 77 and 78 are caused to grip the wire,and immediately after the warp-eye-forming tool 88h and the anviljaws89d and 89e are also brought forward into engagement, as shown at Fig.10. lVhen, therefore, the parts thus described are enga ged, thewinding-shafts will make a quarter of a revolution,brin ging the grooves85 and 85n of the said shafts and chucks to the front, as shown at Fig.3, so as to bring the doubles'tranded wires in a horizontal position andthe two jaws of the end chucks 72 and 75 in a vertical position, (seealso Fig. 23,) so that the ends of the wires may be thrown between saidjaws and the body of said wires, together with such ends, may be firmlygripped. In the meantime the cutting-off tool 55 is actuated to severthe wires. Then the initial bending-tools 56 and 56 are brought forwardto give a right-angle bend, Fig. 22, to the ends of the wires about theformers 64 and 64b, which formers have previously descended in readinessto be engaged with said wires. Vhen the ends of the wires are in theposition shown at Fig. 22, the folders, Fig. 23, 46 and 4Gb are broughtforward to embrace the formers 64 and 64b and the wires about the same.It will be observed that the forked opening in these folders, Fig. 2l,is smaller at the mouth or entrance than at the bottom. This feature ofconstruction enables the narrow mouth to spring firmly against the wiresmain body of the vertically-operated former and by so doing be sure tothrow the free ends of the heddle-wires against the main body, so thatthey may all be uniformlyV gripped by the outer jaws 7 (3 and 79. Afterthe` ends of the wires are in the position just described and before thejaws descend the centering devices (shown at Figs. 18, 19, and 20 andpreviously described) are brought into engagement with the wires, so asto locate them directly within the gripping-field of the jaws, whereuponsaid jaws will engage and the winding-shafts will make one completerevolution and halt long enough for the center jaws 77 and 78, Fig. 2l,to be released and also the warp-eye-forming tool 881 and the anvil-jaws89d and 89e to retreat to their normal position. The winding-shafts willthen re- `start to form the longer twists, Figs. 24 and 25, close to therod-eye of the heddle. 'lVhen the winding process at the ends orrod-eyes begins, the inevitable tendency is to shorten the distancebetween the central or warp eye and the said rod-eyes. To compensate forthis, or, in other words, to relieve all strain on the twin wires nowsuspended between the two end formers 64 64C, means are provided wherebysaid formers may move toward the center of the machine a distancesuflicient to overcome this shortening tend- 4after said narrow mouthhas passed by the ency. For this purpose the upper forked end of saidformers 64 and G4" (see Figs. 2, 3, 12, and 13) is considerably widerthan is necessary to merely support the tilting levers 59 59 on theirpivotal pins 63 93a, so that when the heddle begins to shorten under thetwisting process just described the said formers, togetherwith theslides to which they are attached, will be drawn in the direction of thearrows c e, Figs. 2 and 3, and the space between the face of one of saidforks and the face of the levers 59 and 59 will represent the distancethe two slides 49 and 49n will need to travel in order to compensate forthe contraction of the heddle due to the said Winding process.

It will be observed that the several chucks 72 73 74 75, Figs. 2 and 8,are provided with slots 72h, 73, 74a, and 75LL to coincide with theslotted winding-shafts 67 and 67, so that when the winding process isfully completed the said shafts will be temporarily halted in line withthe openings 98, Figs. 8, 9, 11, and 18, in the bed of the machine, andwhile thus halted the rod-eye formers will be carried up, so as to stripthe completed heddle therefrom, and such completed heddle will then dropthrough the bed, after which operation the said shafts will return totheir normal position in readiness to receive the necessary complementof wire to form another heddle.

99, Figs. 1, 12, and 13, are retractilesprings attached to the twoprimary end slides to bring them back to their normal position.

It will be understood that the twister or Winding shafts may be rotatedin opposite di-` IOC) rection, if desired, instead of rotating in thesame direction, as shown. A
